Example Embodiment

[0035] Example 1

[0036] In this technical solution, the light-emitting body adopts polarized straw hat lamp beads, and the polarized straw hat lamp beads are arranged on the outer periphery of the carrier in the same way. The straw hat lamp beads include a bracket 1, an internal reflector 2, and a package lens 3. and LED chip 4.

[0037] Further, in order to make the polarized light of the illuminant downward, reduce the waste of light source, and reduce the glare angle, refer to Figure 7 The specific structure of the straw hat lamp beads used in this technical solution is as follows:

[0038] The internal reflector 2 is a "bowl-shaped" internal reflector 2, the diameter of its opening is larger than the diameter of the bottom, the LED chip 4 is placed at the bottom of the internal reflector 2, and the internal reflector 2 is inclined at a certain angle. on the bracket 1; the encapsulation lens encapsulates the internal reflector 2 and the LED chip 4; the encapsulation le...

Example Embodiment

[0043] Embodiment 2

[0044] see Figure 9 , and the difference from the above technical solution is that the curved surface of the package lens 3 is asymmetrical at C90°-270°. If the bottom surface of the internal reflector is not inclined, the incident light 5 will be refracted on the surface of the lens, and will not be emitted in the direction of the original incident light 6, but will become the direction of the refracted light 7. The lamp beads of this structure only rely on the asymmetric shape of the lens to change the direction of the light.

Example Embodiment

[0045] Embodiment 3

[0046] see Figure 10 , Different from the above technical solutions, the bottom surface of the LED chip is inclined, the inclination direction is uncertain, the curved surface of the package lens 3 is in the shape of the central axis of the lamp bead, the LED lamp bead of this structure can rely on the inclined LED chip and package. The cooperation of the lens 3 makes the final light output direction tilted and deflected.

Abstract

The invention provides a light emitter which comprises a carrier and a driving power supply which is arranged inside the carrier, wherein beads are installed at the periphery of the carrier; a plurality of rows of beads are uniformly arranged at the periphery of the carrier; and the beads are of polarized light type straw hat beads. By adopting the polarized light type straw hat beads, the light emitter can be combined into a polarized light type LED (light emitting diode) light emitter without an external reflector, but the straw hat beads adopting a polarized light type design and one-time light distribution are used as a light source foundation, full angles of the straw hat beads are controlled as 100 degrees, a lamp shielding angle at one single side is 50 degrees, the polarized light of the light emitter is ejected out downwards in a certain angle, so that direct glare of a lamp is reduced, and a radiation range and brightness of the light emitter are reasonable.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a luminous body. Background technique [0002] In the context of the current global energy shortage concerns rising again, the energy issue is an important issue we face in the future. In the field of lighting, the application of LED products is attracting the attention of the world. LED has many advantages such as low power consumption, long service life, energy saving, and environmental protection. It is more and more widely used in various fields. It is a new light source in the 21st century. It has the incomparable advantages of traditional light sources such as high efficiency, fast response time, and not easily damaged. [0003] The LED lamp bead has a large luminous angle. In order to make the lamp suitable for large-scale lighting occasions, the LED lamp bead is usually installed on the main body of the rod-shaped lamp to form a 360° light. Its shape is like a corn cob,...
